LOCKING DEVICE.

Application led December 7, 1923. Serial No. 679,203.

T 0 all whom t may concern Be it known that I, JnNs C. JENSEN, a citizen of the United States, residing at Chicago, in the county ot' Cook and State of Illinois, have invented a new and useiul Improvement in Locking Devices, ot which the following is a specification.

This invention relates to locking hinges and the like and is particularly adapted to be used on French windows which swing into closing position at one elevation and when substantially closed drops a haltl inch or more so as to seal the window at the bottom thereby among other things, preventing water from flowing in around the bottom of the window.

The invention is fully described in the following specification and shown in the accompanying drawing in which:

Figure 1, is a front inside elevation of a window having the invention applied there- 2 is a horizontal section on the line 2-2 of Fig. 1;

Figs. 3 and 4 are enlarged vertical sections on the lines 3 and t of Fig. 1;

Fig. 5 is an elevation or the hinge in open position;

Fig. 6 is an inside edge view of the hinge in closed position;

Fig. 7 is a section on the line 8 of Fig. 4 showing the position of the hinge with the window raised; and

Fig. 8 is a similar section showing the position of the hinge with the window lowered.

The embodiment illustrated comprises a French window 10 set in a suitable casing 11. A t the top of the window is a three knuckle hinge 12, the middle and upper knuckle 13 and 14 respectively having been cut away as shown in Figs. 1 and 8 to permit the upper knuckle 14: to slide past the shoulder 18l of the middle knuckle when the window is in lowered position as shown in Fig. 1, thereby leaving a space 15 between the middle and lower knuckles 13 and 12. 1t will be understood that the centre knuckle 18 is secured to the frame while the hinge having knuckles 12 and 14 is secured to the window sash.

1With a set of hinges such as that which has been just described and which are well known in this art, the operator opening the window would grasp the handle 16 raise the window 10 until the lower hinge knuckle 12 struck the middle hinge knuckle 18; when the window 10 would be high enough to permit it to swing out over the sill 1.7 as shown in Fig. 4L.

For the purpose ot obtaining an even closer engagement between the window and the frame, l have provided a vertical metal strip 18 which is secured to the window sill and which passes up into the slot 19 in the bottom of the window sash when the latter is lowered in the closed position as shown in Fig. 1.

`With the foregoing arrangement, however, it is necessary for the operator to hold the window in the raised position unless the window itself is swung out at which time the lower edge oic the upper knuckle 14 rests upon the top of the port-ion 18a. For some purposes, however, it is inconvenient to permit the window in this raised position and it is desirable to have it immediately drop back to the closed position without being so held. The present invention provides a hinge which is shown at the lower portion of the window which provides a means for automatically holding the window in the raised position once it has been raised until that window is opened a predetermined distance.

rI'his hinge comprises hinge members 20 and 21 which are secured respectively to the sash 10 and frame 11 and having vthe usual pin 22 hingedly connecting them. The hinge member 2O has knuckles 28 and 211, the latter being cut away at 25 to permit it to pass a similar cut away portion 2G on the knuckle 27 of the hinge member 21. A metal linger 28 is secured to the hinge member 2O by means ot' screws 29 and 30 and is pressed against the outer sui-tace ot' the member 2O by means of springs 81 and 32. A slot 33 is provided in the hinge member 2O which is adapted to pass over the pin 34 in the hinge member 21. The pin extends through this slot as shown in Fig. 7 and encounters the upper edge of the ringer 28 which is somewhat loosely mounted on the pins 29 and 8O so that as the sash is raised the inger 28 will strike the pin 34e as shown in Fig. 7 and will hold 1t m the proper position to cause it to snap into the cut away space in the central' knuckle when the sash is completely raised as shown in Fig. 6. L

It will be understood from the foregoing that as the window sash is raised the finger 28 ot sheet metal will pass into the space between the center knuckle 27 and the upper knuckle 24 and will stay therein until released as will now be explained.

For this purpose a pin 35 is carried by the central knuckle 27 and is adapted to encounter the rounded lower corner 281 of the finger 28 as the window is swung outward. This causes the linger 28 to be raised outwardly and upwardly so that when the window is again swung inward the iinger 28 will ride up over the upper' knuckle 2li so that when the window is again swung to closing position it will not prevent the sash from dropping' to the position shown in Fig. et.

On again raising the window sash,l however, the upper edge of the finger 28 will again encounter the pin 84 thereby causing it to snap into the space beneath the` knuckle 24 in which position it will remain until it is again reraised as has been previously described.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modiiications. Changes therefore in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as possible in View of the prior art.

I claim:

1. In a hinge, two members having alternately placed knuckles, a pin passing through said knuckles, two 'adjacent knuck les being partially out away'to permit said members to move longitudinally out ot alignment with respect to each other when swung to closed position and means for holding said members in alignment in closed position when the swinging member is again raised to aligning position with the other member.

2. In a hinge, two members having alternately placed knuckles, a pin passing through said knuckles, two adjacent knuckles being partially cut away to permit said members` to move longitudinally out of alignment with respect to each other when swung to closed position and spring pressed means for holding said members in alignment in closed position when the swinging member is again raised to aligning position with the other member. 3. In a hinge, two members having alternately placed knuckles, a pin passing through said knuckles, two adjacent knuckles being partially cut away to permit said members to nieve longitudinally out of alignment with respect to each other when swung to closed position and means movable into the cut away portion of said knuckles for holding said members in alignment in closed position when the swinging member is again raised to aligning position with the other member.

l. In a hinge, two members having alternately placed knuckles, a pin passing through said knuckles', two adjacent knuckles being partially cut away to permit said members to move longitudinally out ot alignment with respect to each other when swung to closed position and a finger movable into the cut away portion of said knuckles Ytor holding said members in alignment. when the swinging member is again raised to aligning position with the other member, and means operable on opening said hinge to disengage said finger on an opening movement of the hinge.

5. In a hinge, two members having alternately placed knuckles, ya pin passing through said knuckles, twoA adjacentknuckles being partially cut away to permit said members to move longitudinally out of alignment with respect to each other when swung to closed position and a finger movable into the cut away portion of said knuckles for holding said members in alignment. when the swinging member is again raised to aligning position with the other member, said linger being carried by one member and an abutment on the other member for raising said linger out of said cutaway portion on an opening movement of the hinge.

In witness whereof I have hereunto set my hand and seal this 3rd day of December 1923.

JENS C. JENSEN.
